    Assessing the Use Magnesium Chloride as a Dust Suppressant
    (Uganda Christian University, 2025-04-17) Nowamani Gilbert
    This research was conducted in Kayunga district having a main objective of assessing the use of magnesium chloride as a dust suppressant. This study was conducted due to dust clouds along Bbaale-Galilaya road(unpaved) that reduce visibility on the road therefore resulting into vehicle accidents thus leading to loss of lives. The main aim of this study is to efficiently suppress dust while respecting environmental health. This study had three objectives which were determining the concentration of particulate matter present along Bbaale-Galilaya road, to determine the different properties of magnesium chloride and to determine the optimum magnesium chloride required to suppress dust along Bbaale-Galilaya road. In this study, a Blatan Air Quality Machine and a Dust TrackTM machine were used to determine the concentration of particulate matter along the unpaved road and it was found that the PM2.5 was above the provided 24-hour standards of EPA(<35µg/m3) and WHO (<15µg/m3). The study recommended the use of Magnesium Chloride as a dust suppressant along Bbaale-Galilaya road after discovering that 15% MgCl2 concentration reduced PM2.5 levels by 80% (from 143µg/m3 to 28.5µg/m3) while complying with environmental safety guidelines provided by EPA and FAO.
